Industrial PMR edge controllers are purpose-built industrial hardware units designed to operate reliably inside machine electrical control cabinets and harsh factory environments.

Edge Device Models

Industrial PMR consists of strictly two device models, representing the evolution of our edge monitoring technology:
The ipmr223m-v1 is ideal for machines requiring purely operational cycle counting, stroke timing, and run/idle status. The ipmr226 is the refined all-in-one standard for heavy machinery (such as injection molding machines, presses, and extruders) where comprehensive 3-phase electrical monitoring and production output must be captured simultaneously in a single unit.

Physical Enclosure & Terminal Interfaces

Both models are housed in standard 35mm DIN-rail mountable, flame-retardant industrial enclosures. Below are the physical terminal configurations for each model:

1. ipmr223m-v1 (Older, Simpler Node)

Designed for streamlined machine cycle counting with minimal cabinet wiring footprint:

2. ipmr226 (New, Refined Controller with Integrated Power Analyzer)

Engineered for simultaneous 3-phase energy auditing and comprehensive production monitoring:

External Wiring Standards

Digital Machine Pulse & Cycle Inputs (Both Models)

  • Sensor Compatibility: Accepts standard 5V to 24V DC PNP/NPN proximity sensors, optical photo-eyes, or mechanical limit switches.
  • Optoisolation: All digital inputs feature 2.5 kV optical isolation to safeguard internal logic circuitry from factory ground loops and inductive spikes.
  • Wiring: Connect the sensor switched signal lead to IN1 (or IN2) and the sensor reference return to GND.

3-Phase Power Analyzer Connections (ipmr226 Exclusively)

  • AC Voltage Sensing (L1, L2, L3, N):
    • Tap off downstream of the main machine isolator through a dedicated 3-pole 2A or 6A miniature circuit breaker (MCB).
    • Phase lines L1(R)L1 (R), L2(Y)L2 (Y), L3(B)L3 (B), and Neutral (NN) enable continuous line-to-neutral and line-to-line true RMS voltage monitoring.
  • Current Transducers (CT-R, CT-Y, CT-B):
    • Clamp split-core CTs around the insulated phase conductors supplying the machine load or main motor.
    • Orientation: Ensure the directional arrow on each CT points toward the load (machine), away from the supply breaker.
    • Connect the CT secondary leads to the corresponding terminals (CT-R, CT-Y, CT-B) and common GND.

Diagnostic LED Status Indicators

Both edge controllers feature front-panel multi-color diagnostic LEDs for rapid visual inspection:

Physical Installation Guidelines

  1. Power Isolation: Always de-energize and lock out the machine main electrical panel before opening the cabinet doors.
  2. DIN Rail Placement: Mount the node on a standard 35mm DIN rail with a minimum 50mm clearance from high-frequency Variable Frequency Drives (VFDs) and heavy contactor coils to prevent inductive electromagnetic interference (EMI).
  3. Antenna Routing: For steel electrical cabinets, route the external high-gain antenna through an enclosure knockout to ensure strong Wi-Fi signal propagation (-65 dBm or better).
  4. BLE Commissioning: Follow the BLE Provisioning Guide to configure plant Wi-Fi credentials from a mobile phone or tablet without connecting physical serial cables.
